1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on Orice holder for dust and dirt
(see Figures 36 and 37).
3. Blow air through the ports/slots and holes
in the burner.
4. Check the Orice holder located at the
end of the burner tube again. Remove
any large particles of dust, dirt, lint or pet
hair with a soft cloth or vacuum cleaner
nozzle.
5. Blow air into the primary air holes on the
Orice holder.
6. In case any large clumps of dust have now
been pushed into the burner repeat steps
3 and 4.
Clean the pilot assembly also. A yellow tip
on the pilot ame indicates dust and dirt in
the pilot assembly. There is a small pilot air
inlet hole about two inches from where the
pilot ame comes out of the pilot assembly
(see Figure 37). With the unit off, lightly blow
air through the air inlet hole. You may blow
through a drinking straw if compressed air is
not available.
CLEANING AND MAINTENANCE

LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 16, to properly replace
logs.
• Replace log(s) if broken or chipped (dime-
sized or larger).
MAIN BURNER
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame pres-
ent. All round burner ame holes should be
open with a small blue ame present. Some
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner ame holes will create soot.
